I finally decided to upgrade my graphics card from the stock that came with my computer to one that could handle DirectX 10.1, and I've noticed an improvement with my graphics right away.It also made it so I could see terminal building at night (before I only had jet ways attached to nothing).Unfortunately the textures to most of my add-on aircraft (like POSKY) are blank. Even the ones that are supposed to work with FSX. The AI planes are fine.I have 2 questions:#1, Why? Is there a format difference with DirectX (the textures worked before I enabled DirectX) that makes older textures not recognizable by FSX?#2, What solutions are available?

DirectX 9 work OK in FSX. DirectX 10 is only a "preview" of DX10 and doesn't work OK IMO.There are add ons that doesn't work with DX10.

So I unclicked DX10, and the nighttime airport textures disappeared (this is a major reason for me upgrading to the graphics card). I'm curiuos what is making this happen. I haven't tried any flights with the new graphics card and not using DX10, so I'm not sure if that is an improvement (it probably is).Again, this only happens during the night. I lose my ATC taxi path, and lose the terminal. The ATC path is annoying, but not a huge deal. The terminal issue makes FSX look goofy.W/O the card it was working fine, except for the terrain would go light blue while flying at cruise (didn't look very good).
